Common problems we fix in Holland Park

Sunlight breaks sealant down, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip to the glass and frame.

It’s worth asking for a quote if you see:

  • Sealant that was laid over old silicone and failed
  • Split or lifting silicone on glass
  • Drips on the inside of a conservatory window
  • Mouldy sealant around glass panels

As a London address, Holland Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Questions to ask before booking

  • How long the guarantee is
  • How the surfaces are prepared before sealing

10 questions to ask before booking

Glazing silicone in Holland Park, done properly

Glazing joints need a sealant made for glass. Our applicators use neutral-cure glazing silicone that’s suited to glass and the frame, finished with a neat, even bead. We work on glass balustrade bases, glass-to-frame joints and rooflights, and people most often call us about stained, discoloured glazing silicone and new silicone smeared over old sealant.

London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.

A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Landlord and commercial work in Holland Park

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

When it is not the sealant

Honest advice matters more to us than a booking, so here’s what sealant cannot fix:

  • A sealed unit that has misted inside
  • A sagging or failing conservatory roof
  • Failed flashing around a conservatory

If in doubt, ring 0345 464 0079 or email us and we will say what we think.

DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

Glazing silicone in Holland Park: local notes

In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking. With historic houses such as Leighton House (about 0.4 miles south) nearby, there’s older building stock in the area around Holland Park as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

Rented homes near Kensington Olympia station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. For site and facilities teams at buildings such as Holland Park School, larger buildings have plenty of frames, and the mastic around each one ages.

FAQs for Holland Park

Do you cover Holland Park for glazing silicone?

Yes, Holland Park is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.

Can you help a landlord with a rental near Kensington Olympia station?

Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.

Why not top up the existing silicone?

A top-up rarely holds. The new bead cannot grip the old one, so we remove the old sealant and clean the joint.

Can I do it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

What information do you need?

Tell us what needs doing and where, with pictures by email if possible. We will ask anything else we need to know.

Can I add another job to the visit?

Of course. Combining jobs makes good use of the visit.

Do you replace glass?

No. We renew the sealant. Glass and sealed units need a glazier.

Is a special sealant needed for glass?

We pick a glazing silicone to suit the materials. Neutral-cure products suit most glass and frames.

What we do, step by step

You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for most jobs in most cases. For a job in Holland Park, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.

  1. First, we trace the leak and check it’s coming through a sealant joint.
  2. We cut out the failed silicone, taking care of the glass and frame.
  3. Surfaces are cleaned with a solvent suited to glass and the frame.
  4. Glazing silicone suited to the joint is applied and tooled.
  5. The finished joints are checked and, where it’s safe, tested with water.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • Keep children and pets away from the work area
  • Clear items away from the joints we are working on
